lamno3 and lamno3/zsm-5 nano catalysts were synthesized by pechini method and their physical-chemical properties were characterized using xrd, ftir, sem-edx, uv-vis drs, bet surface area and tpr. the correlation between characteristic properties and activity of catalysts were investigated. the catalytic performance of the catalysts was evaluated in combustion of 2-propanol and compared with 1% ...

The most studied catalysts for methane dehydroaromatization (MDA)?Mo/ZSM-5?are not commercialized yet due to the rapid deactivation and insufficient activity. Catalytic systems based on Fe Re are potential alternatives Mo-containing zeolites. Here, we compare catalytic performance of these as a function metal type its loading in ZSM-5 zeolite. results show that activity decreases order Re/ZSM-5...

The selective catalytic reduction (SCR) of NO by methane in the presence of excess oxygen has been studied on a series of Pd catalysts supported on sulfated zirconia (SZ). This support is not as sensitive to structural damage by steaming as the acidic zeolites, such as H-ZSM-5 and H-Mor. In previous studies, it was shown that this type of acidic zeolites are able to stabilize Pd2+ ions and prom...

This paper presents the results of isotherm and basic (Δ H , Δ F, S ) thermodynamic characteristics ammonia adsorption in Na zeolites 2,87 ZSM-5 Li 3,37 ZSM-5; also is described by bulk micro-pore filling theory (BFM) equations. The correlation between adsorption-energy found, molecular mechanism whole region revealed. adsorbed NaZSM-5 LiZSM-5 located first coordination sphere with + cations, f...
